sync error with new iphone 5

I just upgraded from an iphone 3gs to iphone 5. I am keeping my 3gs to use without cell service but only with wifi. Synching my notebooks with my 3gs works just fine but when I try to sync my iphone 5 I get the following error:
Notebook Sync Error
Failed to connect with Toodledo.com

I had the same problem. This is the fix I received from my "support ticket". I deleted as below and readded and it worked.

Thank you for contacting Appigo Support. I will do my best to assist you.

Are all of your notes currently in Toodledo?

If all of your notes are in Toodledo currently then do the following:
-Delete your Toodledo collection by swiping from left to right over the collection name
-Once the collection has been deleted, add the collection again.
